Field studies of discoloration in water distribution systems: model verification and practical implications.

摘要: Discoloration in water distribution systems has been studied partnership with a number of U.K. companies by measuring the turbidity response to changes hydraulic conditions induced systematic flushing. The resulting data was used verify predictive empirical model and hence underlying assumptions made its development. Model simulations, using previously established parameters defined solely pipe diameter material, are presented alongside measured demonstrate this verification. primary cause discoloration observed is mobilization material from cohesive layers bonded walls. These profile increasing shear strength degree discoloration. Differences demonstrated layer ultimate characteristics formed iron plastic pipes, modeled stress 1.2 N/ m2 shown exhaust pipes. Based on d...
